Filed: 1967-05-03
Abstract: 1,220,332. Producing fuel elements by electroforming. BRISTOL AEROJET Ltd. April 29, 1968 [May 3, 1967], No.20474/67. Heading C7B. [Also in Division G6] A fuel element comprising particles of fissile material in a metal matrix is manufactured by electro-forming in a bath for the electro-deposition of the matrix material and containing particles of the fissile material. During this process the fissile particles are entrapped by the matrix material being electro-deposited so that a composite coating of particles dispersed in a metal matrix is built up. The fissile material may be uranium dioxide or plutonium and the matrix material may be nickel. In an example a cylindrical fuel element is formed by electro-plating on a copper rod serving as a cathode and a nickel rod is used as an anode in a solution containing nickel sulphamate, nickel chloride and sodium formate. Particles of fissile material are maintained in suspension in the solution by admitting air into the lower part of the bath. The air-flow is stopped after a desired time and the fissile particles are allowed to settle. The plating process is then continued to plate a layer of pure nickel on the element. Finally, the copper rod is dissolved away.

Title: Method and apparatus for the production of a mixture of hydrogen and steam
IPC: C10J3/00
Filed: 1965-05-14
Abstract: <PICT:1107002/C1/1> A process for preparing a mixture of hydrogen and steam comprises (a) the reacting steam and air with carbonaceous materials in a first reaction zone to generate producer gas, (b) reacting the said producer gas with iron oxide in a second reaction zone to reduce the oxide to a low oxide and metallic iron, (c) reacting a lower oxide and metallic iron produced in step (b) with steam in a third reaction zone to produce hydrogen and steam, (d) reacting the spent producer gas from reduction of iron oxide with carbonaceous material and air in a first generating zone to enrich the spent producer gas in hydrogen and carbon monoxide, (e) reacting the enriched producer gas with iron oxide in a fifth reaction zone to reduce the oxide to a lower oxide and metallic iron, and reacting the lower oxide and metallic iron from step (e) with steam in a sixth reaction zone to produce additional hydrogen and steam.  The carbonaceous material may be char from a hydrogasifier.  In the Figure, conduit 3 feeds char from the hydrogasifier 1 to a first gas producer 4 and a second gas producer 5.  Steam and air heated in an exchanger 6 flow to gas producer 4 and flows through the char which may be as a fluidized bed.  Producer gas flows through 8 to exchanger 6 and then through 9 to first reductor 10 containing iron oxide fed in by steam or gas lift 11.  The producer gas leaving 4 has a temperature of 1700 DEG  to 2000 DEG  F. and is cooled to 1400 DEG F.  The reduction in 10 is at 1400 DEG  F. to 1500 DEG  F.  The bed in 10 may be fluidized or three-falling.  Reduced oxide passes to oxidizer 13 into which steam flows through 14.  Hydrogen and steam both flow through 13a and 1a to hydrogasifier 1.  The spent producer gas passes to second gas producer 5 to react with char supplied through 3 and air heated in 16 supplied through 17.  The temperature inside is 1700 DEG  to 2000 DEG  F.  Enriched producer gas flows to 16 and then through 19 to second iron reductor 20.  Iron enters through fluid lift 21 and reduced oxide flows through 22 and into second oxidizer 23. Steam and hydrogen from 23 flow to hydrogasifier 1 through 24 and 1a.  Spent producer gas from 20 flows via 25 and expander compressor 26 and conduit 27 to waste heat boiler 28 and exit through 29.  Expander compressor 26 blows air through 30, 31 and 32 to producer 4 and also through 30 and 33 to producer 5. Waste heat boiler 28 delivers steam to producer 4 to oxidizers 13 and 23.  The steam hydrogen mixture flows to the hydrogasifier 1 and then to waste heat boiler 36 and to purifier 38. Hydrogen and carbon monoxide flow through 39 to catalytic methanation reactor 40, final product gas emerging from conduit 41.

Patent GB-944703-A (GB)
Title: Method of producing siloxanes having different siloxane units
IPC: C08G77/48
Filed: 1960-06-10
Abstract: A siloxane having different siloxane units is made by hydrolysing an equilibrated organosilicon polymer having different siloxane units and the average general formula <FORM:0944703/C3/1> in which each R is H or a substituted or unsubstituted hydrocarbon radical, X is halogen or an alkoxy radical, a is 0.9 to 2.2, u is 0.75 to 1.5, v is 0.0001 to 0.5 and 4>(a-2u+2v)>2. The R radicals may be, e.g. methyl, ethyl, cyclohexyl, phenyl, 4-chlorophenyl, 3-fluoropropyl, 3-acetoxypropyl, or 3-cyanopropyl. The starting polymers containing the sulphate and hydrolysable groups are those described in Specification 899,148 and those made in a similar manner but using tetra-, tri- or monofunctional silanes instead of difunctional ones. The starting polymer or mixtures of polymers can be equilibrated with an organo-halo- or organoalkoxy silane of which the organic radicals are at least in part different from those of the polymer, and the resulting product is then hydrolysed.  The hydrolysis may be effect is several stages, each stage being followed by equilibration with the silane, and finally any remaining hydrolysable groups are hydrolysed. In a typical example (1) a polymer containing Si-bonded halogen and sulphate groups was mixed with methyl dichlorosilane and tri-methyl-silylsulphate and stirred at 20 DEG C. for 18 hours, volatile constituents being subsequently removed by vacuum distillation; the residue was introduced dropwise into a mixture of water and tetrahydrofuran to yield, on purification, a siloxane oil containing Si-bonded hydrogen.
